Re: It's all a matter of perspective
A theory is method of predicting a reult fro a set of parameters, such that the result is ALWAYS correct, under all circumstances. If the result is not ALWAYS correct, then the theory is WRONG. If the theory is ALWAYS shown to be correct, it may be elevated to a Law. i.e, the Laws of Gravity, The Law of Conservation of Energy, the Inverse Square law, etc..
As to a theory in science being more robust than an inspired guess. If you remove the ;science' then you remove the 'inspired'. It becomes a mere guess, and has no validity.
If we take the plethora of climate models, as an example, they are ALL wrong, since they do not predict an actual result, even allowing for measurement and parameter errors. Using the Pythagorian Theorum you can predict the length of the hypotenuse of a right angled triangle, from the length of the other two sides. As anyone who used the early digital computers (eg Sinclair), you did not always get the result as predicted, but that di not invalidate the Theorum, but it has still to be accepted as a Law, despite a very elegant 'proof'.
